Execute(), then when calling ErrorNo() and/or ErrorMsg(), the 1st call
would return the error, but the 2nd call would return no error.</p>
<p>Error handling in odbc bugfix. ODBC would always return the last
error, even if it happened 5 queries ago. Now we reset the errormsg to
'' and errorno to 0 everytime before CacheExecute() and Execute().</p>

</p>
<p>Fixed some oci8 MetaColumns/MetaPrimaryKeys bugs. Thx to Walt
Boring.</p>
<p>adodb_getcount() did not init qryRecs to 0. Missing "WHERE"

<p>We now SET CONCAT_NULL_YIELDS_NULL OFF for odbc_mssql driver to
be compat with mssql driver.</p>
<p>The property $emptyDate missing from connection class. Also
changed 1903 to constant (TIMESTAMP_FIRST_YEAR=100). Thx to Sebastiaan
van Stijn.</p>
<p>ADOdb speedup optimization - we now return all arrays by
reference.</p>
<p>Now DBDate() and DBTimeStamp() now accepts the string 'null' as a
parameter. Suggested by vincent.</p>
<p>Added GetArray() to connection class.</p>
<p>Added not_null check in informix metacolumns().</p>
<p>Connection parameters for postgresql did not work correctly when
port was defined.</p>
<p>DB2 is now a tested driver, making adodb 100% compatible.
Extensive changes to odbc driver for DB2, including implementing
serverinfo() and SQLDate(), switching to SQL_CUR_USE_ODBC as the cursor
mode, and lastAffectedRows and SelectLimit() fixes.</p>
<p>The odbc driver's FetchField() field names did not obey
ADODB_ASSOC_CASE. Fixed.</p>
<p>Some bugs in adodb_backtrace() fixed.</p>
<p>Added "INT IDENTITY" type to adorecordset::MetaType() to support
odbc_mssql properly.</p>

compat with mssql driver.</p>

<p><b>3.50 19 May 2003</b></p>
<p>Fixed mssql compat with FreeTDS. FreeTDS does not implement
mssql_fetch_assoc().
<p>Merged back connection and recordset code into adodb.inc.php.
<p>ADOdb sessions using oracle clobs contributed by
achim.gosse#ddd.de. See adodb-session-clob.php.
<p>Added /s modifier to preg_match everywhere, which ensures that
regex does not stop at /n. Thx Pao-Hsi Huang.
<p>Fixed error in metacolumns() for mssql.
<p>Added time format support for SQLDate.
<p>Image => B added to metatype.
<p>MetaType now checks empty($this->blobSize) instead of
empty($this).
<p>Datadict has beta support for informix, sybase (mapped to mssql),
db2 and generic (which is a fudge).
<p>BlobEncode for postgresql uses pg_escape_bytea, if available.
Needed for compat with 7.3.
<p>Added $ADODB_LANG, to support multiple languages in
MetaErrorMsg().
<p>Datadict can now parse table definition as declarative text.
<p>For DataDict, oci8 autoincrement trigger missing semi-colon.
Fixed.
<p>For DataDict, when REPLACE flag enabled, drop sequence in
datadict for autoincrement field in postgres and oci8.s
<p>Postgresql defaults to template1 database if no database defined
in connect/pconnect.
<p>We now clear _resultid in postgresql if query fails.
<p><b>3.40 19 May 2003</b></p>
<p>Added insert_id for odbc_mssql.
<p>Modified postgresql UpdateBlobFile() because it did not work in
safe mode.
<p>Now connection object is passed to raiseErrorFn as last
parameter. Needed by StartTrans().
<p>Added StartTrans() and CompleteTrans(). It is recommended that
you do not modify transOff, but use the above functions.
<p>oci8po now obeys ADODB_ASSOC_CASE settings.
<p>Added virtualized error codes, using PEAR DB equivalents.
Requires you to manually include adodb-error.inc.php yourself, with
MetaError() and MetaErrorMsg($errno).
<p>GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith.
<p>Added to datadict types I1, I2, I4 and I8. Changed datadict type
'T' to map to timestamp instead of datetime for postgresql.
<p>Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did
not work.
<p>We now auto-quote postgresql connection parameters when building
connection string.
<p>Added session expiry notification.
<p>We now test with odbc mysql - made some changes to odbc recordset
constructor.
<p>MetaColumns now special cases access and other databases for
odbc.
<p><b>3.31 17 March 2003</b></p>
<p>Added row checking for _fetch in postgres.
<p>Added Interval type to MetaType for postgres.
<p>Remapped postgres driver to call postgres7 driver internally.
<p>Adorecordset_array::getarray() did not return array when nRows >=
0.
<p>Postgresql: at times, no error message returned by
pg_result_error() but error message returned in pg_last_error(). Recoded
again.
<p>Interbase blob's now use chunking for updateblob.
<p>Move() did not set EOF correctly. Reported by Jorma T.
<p>We properly support mysql timestamp fields when we are creating
mysql tables using the data-dict interface.
<p>Table regex includes backticks character now.
<p><b>3.30 3 March 2003</b></p>
<p>Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant.
<p>Made blank1stItem configurable using syntax "value:text" in
GetMenu/GetMenu2. Thx to Gabriel Birke.
<p>Previously ADOdb differed from the Microsoft standard because it
did not define what to set $this->fields when EOF was reached. Now at
EOF, ADOdb sets $this->fields to false for all databases, which is
consist with Microsoft's implementation. Postgresql and mysql have
always worked this way (in 3.11 and earlier). If you are experiencing
compatibility problems (and you are not using postgresql nor mysql) on
upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS =
true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a
new global variable).
<p>We now check both pg_result_error and pg_last_error as sometimes
pg_result_error does not display anything. Iman Mayes
<p>We no longer check for magic quotes gpc in Quote().
<p>Misc fixes for table creation in adodb-datadict.inc.php. Thx to
iamsure.
<p>Time calculations use adodb_time library for all negative
timestamps due to problems in Red Hat 7.3 or later. Formerly, only did
this for Windows.
<p>In mssqlpo, we now check if $sql in _query is a string before we
change || to +. This is to support prepared stmts.
<p>Move() and MoveLast() internals changed to support to support EOF
and $this->fields change.
<p>Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas
afradejas#mediafusion.es
<p>We now check if link resource exists before we run
mysql_escape_string in qstr().
<p>Before we flock in csv code, we check that it is not a http url.

<p><b>3.20 17 Feb 2003</b></p>
<p>Added new Data Dictionary classes for creating tables and
indexes. Warning - this is very much alpha quality code. The API can
still change. See adodb/tests/test-datadict.php for more info.
<p>We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates
incomplete recordsets when mysql_unbuffered_query() is called a second
time.
<p>Now postgresql works correctly when $ADODB_COUNTRECS = false.
<p>Changed _adodb_getcount to properly support SELECT DISTINCT.
<p>Discovered that $ADODB_COUNTRECS=true has some problems with
prepared queries - suspect PHP bug.
<p>Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for
better performance.
<p>Added support for mysql_real_escape_string() and
pg_escape_string() in qstr().
<p>Added an intermediate variable for mysql _fetch() and MoveNext()
to store fields, to prevent overwriting field array with boolean when
mysql_fetch_array() returns false.
<p>Made arrays for getinsertsql and getupdatesql case-insensitive.
Suggested by Tim Uckun" tim#diligence.com
<p><b>3.11 11 Feb 2003</b></p>
<p>Added check for ADODB_NEVER_PERSIST constant in PConnect(). If
defined, then PConnect() will actually call non-persistent Connect().
<p>Modified interbase to properly work with Prepare().
<p>Added $this->ibase_timefmt to allow you to change the date and
time format.
<p>Added support for $input_array parameter in CacheFlush().
<p>Added experimental support for dbx, which was then removed when i
found that it was slower than using native calls.
<p>Added MetaPrimaryKeys for mssql and ibase/firebird.
<p>Added new $trim parameter to GetCol and CacheGetCol
<p>Uses updated adodb-time.inc.php 0.06.
<p><b>3.10 27 Jan 2003</b>
<p>Added adodb_date(), adodb_getdate(), adodb_mktime() and
adodb-time.inc.php.
<p>For interbase, added code to handle unlimited number of bind
parameters. From Daniel Hasan daniel#hasan.cl.
<p>Added BlobDecode and UpdateBlob for informix. Thx to Fernando
Ortiz.
<p>Added constant ADODB_WINDOWS. If defined, means that running on
Windows.
<p>Added constant ADODB_PHPVER which stores php version as a hex
num. Removed $ADODB_PHPVER variable.
<p>Felho Bacsi reported a minor white-space regular expression
problem in GetInsertSQL.
<p>Modified ADO to use variant to store _affectedRows
<p>Changed ibase to use base class Replace(). Modified base class
Replace() to support ibase.
<p>Changed odbc to auto-detect when 0 records returned is wrong due
to bad odbc drivers.
<p>Changed mssql to use datetimeconvert ini setting only when 4.30
or later (does not work in 4.23).
<p>ExecuteCursor($stmt, $cursorname, $params) now accepts a new
$params array of additional bind parameters -- William Lovaton
walovaton#yahoo.com.mx.
<p>Added support for sybase_unbuffered_query if ADODB_COUNTRECS ==
false. Thx to chuck may.
<p>Fixed FetchNextObj() bug. Thx to Jorma Tuomainen.
<p>We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx
to marchesini#eside.it
<p>Changed postgresql movenext logic to prevent illegal row number
from being passed to pg_fetch_array().
<p>Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro
$f1 accidentally named $f
<p><b>3.00 6 Jan 2003</b>
<p>Fixed adodb-pear.inc.php syntax error.
<p>Improved _adodb_getcount() to use SELECT COUNT(*) FROM ($sql) for
languages that accept it.
<p>Fixed _adodb_getcount() caching error.
<p>Added sql to retrive table and column info for odbc_mssql.
<p><strong>2.91 3 Jan 2003</strong>
<p>Revised PHP version checking to use $ADODB_PHPVER with legal
values 0x4000, 0x4050, 0x4200, 0x4300.
<p>Added support for bytea fields and oid blobs in postgres by
allowing BlobDecode() to detect and convert non-oid fields. Also added
BlobEncode to postgres when you want to encode oid blobs.
<p>Added blobEncodeType property for connections to inform phpLens
what encoding method to use for blobs.
<p>Added BlobDecode() and BlobEncode() to base ADOConnection class.

<p>Added umask() to _gencachename() when creating directories.
<p>Added charPage for ado drivers, so you can set the code page.
<pre>
$conn->charPage = CP_UTF8;
$conn->Connect($dsn);
</pre>
<p>Modified _seek in mysql to check for num rows=0.
<p>Added to metatypes new informix types for IDS 9.30. Thx Fernando
Ortiz.
<p>_maxrecordcount returned in CachePageExecute $rsreturn
<p>Fixed sybase cacheselectlimit( ) problems
<p>MetaColumns() max_length should use precision for types X and C
for ms access. Fixed.
<p>Speedup of odbc non-SELECT sql statements.
<p>Added support in MetaColumns for Wide Char types for ODBC. We
halve max_length if unicode/wide char.
<p>Added 'B' to types handled by GetUpdateSQL/GetInsertSQL.
<p>Fixed warning message in oci8 driver with $persist variable when
using PConnect.
<p><b>2.90 11 Dec 2002</b>
<p>Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE.
<p>Now MetaType() can accept a field object as the first parameter.

<p>New $arr = $db-&gt;ServerInfo( ) function. Returns
$arr['description'] which is the string description, and
$arr['version'].
<p>PostgreSQL and MSSQL speedups for insert/updates.
<p>Implemented new SetFetchMode() that removes the need to use
$ADODB_FETCH_MODE. Each connection has independant fetchMode.
<p>ADODB_ASSOC_CASE now defaults to 2, use native defaults. This is
because we would break backward compat for too many applications
otherwise.
<p>Patched encrypted sessions to use replace()
<p>The qstr function supports quoting of nulls when escape character
is \
<p>Rewrote bits and pieces of session code to check for time synch
and improve reliability.
<p>Added property ADOConnection::hasTransactions = true/false;
<p>Added CreateSequence and DropSequence functions
<p>Found misplaced MoveNext() in adodb-postgres.inc.php. Fixed.
<p>Sybase SelectLimit not reliable because 'set rowcount' not cached
- fixed.
<p>Moved ADOConnection to adodb-connection.inc.php and ADORecordSet
to adodb-recordset.inc.php. This allows us to use doxygen to generate
documentation. Doxygen doesn't like the classes in the main
adodb.inc.php file for some mysterious reason.
<p><b>2.50, 14 Nov 2002</b>
<p>Added transOff and transCnt properties for disabling (transOff =
true) and tracking transaction status (transCnt>0).
<p>Added inputarray handling into _adodb_pageexecute_all_rows -
"Ross Smith" RossSmith#bnw.com.
<p>Fixed postgresql inconsistencies in date handling.
<p>Added support for mssql_fetch_assoc.
<p>Fixed $ADODB_FETCH_MODE bug in odbc MetaTables() and
MetaPrimaryKeys().
<p>Accidentally declared UnixDate() twice, making adodb incompatible
with php 4.3.0. Fixed.
<p>Fixed pager problems with some databases that returned -1 for
_currentRow on MoveLast() by switching to MoveNext() in
adodb-lib.inc.php.
<p>Also fixed uninited $discard in adodb-lib.inc.php.
<p><b>2.43, 25 Oct 2002</b></p>
Added ADODB_ASSOC_CASE constant to better support ibase and odbc field
names.
<p>Added support for NConnect() for oracle OCINLogin.
<p>Fixed NumCols() bug.
<p>Changed session handler to use Replace() on write.
<p>Fixed oci8 SelectLimit aggregate function bug again.
<p>Rewrote pivoting code.
<p><b>2.42, 4 Oct 2002</b></p>
<p>Fixed ibase_fetch() problem with nulls. Also interbase now does
automatic blob decoding, and is backward compatible. Suggested by Heinz
Hombergs heinz#hhombergs.de.
<p>Fixed postgresql MoveNext() problems when called repeatedly after
EOF. Also suggested by Heinz Hombergs.
<p>PageExecute() does not rewrite queries if SELECT DISTINCT is
used. Requested by hans#velum.net
<p>Added additional fixes to oci8 SelectLimit handling with
aggregate functions - thx to Christian Bugge for reporting the problem.

<p><b>2.41, 2 Oct 2002</b></p>
<p>Fixed ADODB_COUNTRECS bug in odbc. Thx to Joshua Zoshi
jzoshi#hotmail.com.
<p>Increased buffers for adodb-csvlib.inc.php for extremely long sql
from 8192 to 32000.
<p>Revised pivottable.inc.php code. Added better support for
aggregate fields.
<p>Fixed mysql text/blob types problem in MetaTypes base class - thx
to horacio degiorgi.
<p>Added SQLDate($fmt,$date) function, which allows an sql date
format string to be generated - useful for group by's.
<p>Fixed bug in oci8 SelectLimit when offset>100.
<p><b>2.40 4 Sept 2002</b></p>
<p>Added new NLS_DATE_FORMAT property to oci8. Suggested by Laurent
NAVARRO ln#altidev.com
<p>Now use bind parameters in oci8 selectlimit for better
performance.
<p>Fixed interbase replaceQuote for dialect != 1. Thx to "BEGUIN
Pierre-Henri - INFOCOB" phb#infocob.com.
<p>Added white-space check to QA.
<p>Changed unixtimestamp to support fractional seconds (we always
round down/floor the seconds). Thanks to beezly#beezly.org.uk.
<p>Now you can set the trigger_error type your own user-defined type
in adodb-errorhandler.inc.php. Suggested by Claudio Bustos
clbustos#entelchile.net.
<p>Added recordset filters with rsfilter.inc.php.
<p>$conn->_rs2rs does not create a new recordset when it detects it
is of type array. Some trickery there as there seems to be a bug in Zend
Engine
<p>Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo
Costa" pablo#cbsp.com.br.
<p>MetaType() speedup in adodb.inc.php by using hashing instead of
switch. Best performance if constant arrays are supported, as they are
in PHP5.
<p>adodb-session.php now updates only the expiry date if the crc32
check indicates that the data has not been modified.
<p><b>2.31 20 Aug 2002</b></p>
<p>Made changes to pivottable.inc.php due to daniel lucuzaeu's
suggestions (we sum the pivottable column if desired).
<p>Fixed ErrorNo() in postgres so it does not depend on _errorMsg
property.
<p>Robert Tuttle added support for oracle cursors. See
ExecuteCursor().
<p>Fixed Replace() so it works with mysql when updating record where
data has not changed. Reported by Cal Evans (cal#calevans.com).
<p><b>2.30 1 Aug 2002</b></p>
<p>Added pivottable.inc.php. Thanks to daniel.lucazeau#ajornet.com
for the original concept.
<p>Added ADOConnection::outp($msg,$newline) to output error and
debugging messages. Now you can override this using the ADODB_OUTP
constant and use your own output handler.
<p>Changed == to === for 'null' comparison. Reported by
ericquil#yahoo.com
<p>Fixed mssql SelectLimit( ) bug when distinct used.
<p><b>2.30 1 Aug 2002</b></p>
<p>New GetCol() and CacheGetCol() from ross#bnw.com that returns the
first field as a 1 dim array.
<p>We have an empty recordset, but RecordCount() could return -1.
Fixed. Reported by "Jonathan Polansky" jonathan#polansky.com.
<p>We now check for session variable changes using
strlen($sessval).crc32($sessval). Formerly we only used crc32().
<p>Informix SelectLimit() problem with $ADODB_COUNTRECS fixed.
<p>Fixed informix SELECT FIRST x DISTINCT, and not SELECT DISTINCT
FIRST x - reported by F Riosa
<p>Now default adodb error handlers ignores error if @ used.
<p>If you set $conn->autoRollback=true, we auto-rollback persistent
connections for odbc, mysql, oci8, mssql. Default for autoRollback is
false. No need to do so for postgres. As interbase requires a
transaction id (what a flawed api), we don't do it for interbase.
<p>Changed PageExecute() to use non-greedy preg_match when searching
for "FROM" keyword.
<p><b>2.20 9 July 2002</b></p>
<p>Added CacheGetOne($secs2cache,$sql),
CacheGetRow($secs2cache,$sql), CacheGetAll($secs2cache,$sql).
<p>Added $conn->OffsetDate($dayFraction,$date=false) to generate sql
that calcs date offsets. Useful for scheduling appointments.
<p>Added connection properties: leftOuter, rightOuter that hold left
and right outer join operators.
<p>Added connection property: ansiOuter to indicate whether ansi
outer joins supported.
<p>New driver <i>mssqlpo</i>, the portable mssql driver, which
converts string concat operator from || to +.
<p>Fixed ms access bug - SelectLimit() did not support ties - fixed.

<p>Karsten Kraus (Karsten.Kraus#web.de), contributed error-handling
code to ADONewConnection. Unfortunately due to backward compat problems,

<p>adodb_sess_read in adodb-session.php now returns ''correctly -
thanks to Jorma Tuomainen, webmaster#wizactive.com
<p>Mssql driver did not throw EXECUTE errors correctly because
ErrorMsg() and ErrorNo() called in wrong order. Pointed out by Alexios
Fakos. Fixed.
<p>Changed ado to use client cursors. This fixes BeginTran()
problems with ado.
<p>Added handling of timestamp type in ado.
<p>Added to ado_mssql support for insert_id() and affected_rows().
<p>Added support for mssql.datetimeconvert=0, available since php
4.2.0.
<p>Made UnixDate() less strict, so that the time is ignored if
present.
<p>Changed quote() so that it checks for magic_quotes_gpc.
<p>Changed maxblobsize for odbc to default to 64000.
<p><b>2.00 13 May 2002</b></p>
<p>Added drivers <i>informix72</i> for pre-7.3 versions, and <i>oci805</i>
for oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The
postgres and postgres7 drivers are now identical.
<p>Interbase now partially supports ADODB_FETCH_BOTH, by defaulting
to ASSOC mode.
<p>Proper support for blobs in mssql. Also revised blob support code
is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.

<p>Added support for changed odbc_fetch_into api in php 4.2.0 with
$conn-&gt;_has_stupid_odbc_fetch_api_change.
<p>Fixed spelling of tablock locking hint in GenID( ) for mssql.
<p>Added RowLock( ) to several databases, including oci8, informix,
sybase, etc. Fixed where error in mssql RowLock().
<p>Added sysDate and sysTimeStamp properties to most database
drivers. These are the sql functions/constants for that database that
return the current date and current timestamp, and are useful for
portable inserts and updates.
<p>Support for RecordCount() caused date handling in sybase and
mssql to break. Fixed, thanks to Toni Tunkkari, by creating derived
classes for ADORecordSet_array for both databases. Generalized using
arrayClass property. Also to support RecordCount(), changed metatype
handling for ado drivers. Now the type returned in FetchField is no
longer a number, but the 1-char data type returned by MetaType. At the
same time, fixed a lot of date handling. Now mssql support dmy and mdy
date formats. Also speedups in sybase and mssql with preg_match and ^ in
date/timestamp handling. Added support in sybase and mssql for 24 hour
clock in timestamps (no AM/PM).
<p>Extensive revisions to informix driver - thanks to Samuel
CARRIERE samuel_carriere#hotmail.com
<p>Added $ok parameter to CommitTrans($ok) for easy rollbacks.
<p>Fixed odbc MetaColumns and MetaTables to save and restore

constructor. Fixed.
<p>Fixed regex for GetUpdateSQL() and GetInsertSQL() to support more
legal character combinations.
<p><b>1.99 21 April 2002</b></p>
<p>Added emulated RecordCount() to all database drivers if
$ADODB_COUNTRECS = true (which it is by default). Inspired by Cristiano
Duarte (cunha17#uol.com.br).
<p>Unified stored procedure support for mssql and oci8. Parameter()
and PrepareSP() functions implemented.
<p>Added support for SELECT FIRST in informix, modified hasTop
property to support this.
<p>Changed csv driver to handle updates/deletes/inserts properly
(when Execute() returns true). Bind params also work now, and
raiseErrorFn with csv driver. Added csv driver to QA process.
<p>Better error checking in oci8 UpdateBlob() and UpdateBlobFile().

<p>Added TIME type to MySQL - patch by Manfred
h9125297#zechine.wu-wien.ac.at
<p>Prepare/Execute implemented for Interbase/Firebird
<p>Changed some regular expressions to be anchored by /^ $/ for
speed.
<p>Added UnixTimeStamp() and UnixDate() to ADOConnection(). Now
these functions are in both ADOConnection and ADORecordSet classes.
<p>Empty recordsets were not cached - fixed.
<p>Thanks to Gaetano Giunta (g.giunta#libero.it) for the oci8 code
review. We didn't agree on everything, but i hoped we agreed to
disagree!
<p><b>1.90 6 April 2002</b></p>

<p>NextRecordSet() support for mssql. Contributed by "Sven Axelsson"
sven.axelsson#bokochwebb.se
<p>Added blob support for SQL Anywhere. Contributed by Wade Johnson
wade#wadejohnson.de
<p>Fixed some security loopholes in server.php. Server.php also

<p>Generalized GenID() to support odbc and mssql drivers. Mssql no
longer generates GUID's.
<p>Experimental RowLock($table,$where) for mssql.
<p>Properly implemented Prepare() in oci8 and ODBC.
<p>Added Bind() support to oci8 to support Prepare().
<p>Improved error handler. Catches CacheExecute() and GenID() errors
now.
<p>Now if you are running php from the command line, debugging
messages do not output html formating. Not 100% complete, but getting
there.
<p><b>1.81 22 March 2002</b></p>
<p>Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for

does not overwrite existing hint.
<p>New Sybase SQL Anywhere driver. Contributed by Wade Johnson
wade#wadejohnson.de
<p><b>1.80 15 March 2002</b></p>
<p>Redesigned directory structure of ADOdb files. Added new driver
directory where all database drivers reside.
<p>Changed caching algorithm to create subdirectories. Now we scale
better.
<p>Informix driver now supports insert_id(). Contribution by "Andrea
Pinnisi" pinnisi#sysnet.it
<p>Added experimental ISO date and FetchField support for informix.

<p>Fixed a quoting bug in Execute() with bind parameters, causing
problems with blobs.
<p>Mssql driver speedup by 10-15%.
<p>Now in CacheExecute($secs2cache,$sql,...), $secs2cache is
optional. If missing, it will take the value defined in
$connection->cacheSecs (default is 3600 seconds). Note that
CacheSelectLimit(), the secs2cache is still compulsory - sigh.
<p>Sybase SQL Anywhere driver (using ODBC) contributed by Wade

<p>MetaDatabases() for postgres contributed by Phil
pamelant#nerim.net
<p>Mitchell T. Young (mitch#youngfamily.org) contributed informix
driver.
<p>Fixed rs2html() problem. I cannot reproduce, so probably a
problem with pre PHP 4.1.0 versions, when supporting new
ADODB_FETCH_MODEs.
<p>Mattia Rossi (mattia#technologist.com) contributed BlobDecode()
and UpdateBlobFile() for postgresql using the postgres specific
pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will
find this useful. See <a
	href="http://phplens.com/lens/lensforum/msgs.php?id=1262">this
posting</a> for an example of usage.
<p>Added UpdateBlobFile() for uploading files to a database.
<p>Made UpdateBlob() compatible with oci8po driver.
<p>Added noNullStrings support to oci8 driver. Oracle changes all '
' strings to nulls, so you need to set strings to ' ' to prevent the
nullifying of strings. $conn->noNullStrings = true; will do this for you
automatically. This is useful when you define a char column as NOT NULL.

<p>Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds
properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.
<p>Toni Tunkkari added patch for sybase dates. Problem with spaces

<p>CSV driver fix for selectlimit, from Andreas - akaiser#vocote.de.

<P>Gam3r spotted that a global variable was undefined in the session
handler.
<p>Mssql date regex had error. Fixed - reported by Minh Hoang
vb_user#yahoo.com.
<p>DBTimeStamp() and DBDate() now accept iso dates and unix
timestamps. This means that the PostgreSQL handling of dates in
GetInsertSQL() and GetUpdateSQL() can be removed. Also if these
functions are passed '' or null or false, we return a SQL null.
<p>GetInsertSQL() and GetUpdateSQL() now accept a new parameter,
$magicq to indicate whether quotes should be inserted based on magic
quote settings - suggested by dj#4ict.com.
<p>Reformated docs slightly based on suggestions by Chris Small.
<p><b>1.65 28 Dec 2001</b></p>

Absolute to the adodb-lib.inc.php file not set properly. Fixed.
<p>
<p><b>1.62 11 Dec 2001</b></p>
<p>Major speedup of ADOdb for low-end web sites by reducing the php
code loading and compiling cycle. We conditionally compile not so common
functions. Moved csv code to adodb-csvlib.inc.php to reduce
adodb.inc.php parsing. This file is loaded only when the csv/proxy
driver is used, or CacheExecute() is run. Also moved PageExecute(),
GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php. This
reduced the 70K main adodb.inc.php file to 55K, and since at least 20K
of the file is comments, we have reduced 50K of code in adodb.inc.php to
35K. There should be 35% reduction in memory and thus 35% speedup in
compiling the php code for the main adodb.inc.php file.
<p>Highly tuned SelectLimit() for oci8 for massive speed
improvements on large files. Selecting 20 rows starting from the
20,000th row of a table is now 7 times faster. Thx to Tomas V V Cox.
<p>Allow . and # in table definitions in GetInsertSQL and
GetUpdateSQL. See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
<p>Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This
determines the number of records to prefetch in a SELECT statement. Only
used by oci8.</p>
<p>Added high portability Oracle class called oci8po. This uses ?
for bind variables, and lower cases column names.</p>
<p>Now all database drivers support $ADODB_FETCH_MODE, including
interbase, ado, and odbc: ADODB_FETCH_NUM and ADODB_FETCH_ASSOC.
ADODB_FETCH_BOTH is not fully implemented for all database drivers.
<p><b>1.61 Nov 2001</b></p>
<p>Added PO_RecordCount() and PO_Insert_ID(). PO stands for
portable. Pablo Roca [pabloroca#mvps.org]</p>
<p>GenID now returns 0 if not available. Safer is that you should
check $conn->hasGenID for availability.</p>
<p>M'soft ADO we now correctly close recordset in _close()
peterd#telephonetics.co.uk</p>
<p>MSSQL now supports GenID(). It generates a 16-byte GUID from
mssql newid() function.</p>
<p>Changed ereg_replace to preg_replace in SelectLimit. This is a
fix for mssql. Ereg doesn't support t or n! Reported by marino Carlos
xaplo#postnuke-espanol.org</p>
<p>Added $recordset->connection. This is the ADOConnection object
for the recordset. Works with cached and normal recordsets.
Surprisingly, this had no affect on performance!</p>
<p><b>1.54 15 Nov 2001</b></p>
Fixed some more bugs in PageExecute(). I am getting sick of bug in this
and will have to reconsider my QA here. The main issue is that I don't
use PageExecute() and to check whether it is working requires a visual
inspection of the html generated currently. It is possible to write a
test script but it would be quite complicated :(
<p>More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.

<p>
<p><b>1.53 7 Nov 2001</b></p>

<p>Oci8 SelectLimit() speedup by using OCIFetch().
<p>Oci8 was mistakenly reporting errors when $db->debug = true.
<p>If a connection failed with ODBC, it was not correctly reported -
fixed.
<p>_connectionID was inited to -1, changed to false.
<p>Added $rs->FetchRow(), to simplify API, ala PEAR DB
<p>Added PEAR DB compat mode, which is still faster than PEAR! See
adodb-pear.inc.php.
<p>Removed postgres pconnect debugging statement.
<p><b>1.50 31 Oct 2001</b></p>
<p>ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to
ADOFieldObject.
<p>PageExecute() now checks for empty $rs correctly, and the errors
in the docs on this subject have been fixed.
<p>odbc_error() does not return 6 digit error correctly at times.
Implemented workaround.
<p>Added ADORecordSet_empty class. This will speedup
INSERTS/DELETES/UPDATES because the return object created is much
smaller.
<p>Added Prepare() to odbc, and oci8 (but doesn't work properly for
oci8 still).
<p>Made pgsql a synonym for postgre7, and changed SELECT LIMIT to
use OFFSET for compat with postgres 7.2.
<p>Revised adodb-cryptsession.php thanks to Ari.
<p>Set resources to false on _close, to force freeing of resources.

<p>Added adodb-errorhandler.inc.php, adodb-errorpear.inc.php and
raiseErrorFn on Freek's urging.
<p>GetRowAssoc($toUpper=true): $toUpper added as default.
<p>Errors when connecting to a database were not captured formerly.

<p>"Nicola Fankhauser" &lt;nicola.fankhauser#couniq.com> found some
bugs in date handling for mssql.</p>
<p>Added minimal Oracle support for LOBs. Still under development.</p>
Added $ADODB_FETCH_MODE so you can control whether recordsets return
arrays which are numeric, associative or both. This is a global variable
you set. Currently only MySQL, Oci8, Postgres drivers support this.
<p>PostgreSQL properly closes recordsets now. Reported by several
people.
<p>Added UpdateBlob() for Oracle. A hack to make it easier to save
blobs.
<p>Oracle timestamps did not display properly. Fixed.
